Working fine CoreXY with 3 steppers on X, 3 on Y, 3 on Z and one E. As seen on 3D Sweden Meetup. Though still same error about "homing file not found" after first reset. Tried printing at 300mm/s and travel at 600mm/s with 80 steps/mm.

Though still same error about "homing file not found" after first reset.

What is the exact error message?

ben_van

Thank you for adding the option to set the minimum movement speed! Now i can work all axes in mm.. However it seems like there is also a minimum limit of 1mm/s applied to G0 moves as well? In my config file I set this:

M203 X2500 Y2500 Z20 E10000 I1

If I send G1 Z5 F20; the commanded speed is correct.
If I send G0 Z5; The max feedrate set in M203 is not honoured and it commands 1mm/s or F60.
This doesn't really bother me except that all of the motion buttons on the PanelDue and Webcontrol send a G0.. Or am I missing something??

Are you running the machine in CNC mode (using M453) or in the default FDM mode? In CNC mode, G0 should use the maximum feed rate. In FDM mode, it uses the same feed rate as G1 commands.

Is this specific to firmware 2.03RC2, or does it happen in 2.02 as well? If it isn't specific to 2.03RC2, please create a separate thread for your issue.

dc42

There are some known issues with firmware 2.03RC2 on CNC machines when using workplace coordinates, so please do not use workplace coordinates with this release.

I am running the machine in laser mode (M452). Previously when i was using older firmware, and had the Z axis in steps per micron, G0 moves would take the max feedrate set in M203. They do also on this release, however only for the X and Y axis, not Z.

dc42

That's odd because X Y and Z should be treated in exactly the same way. Please post your config.g file.

Anyone having issues with babystepping not working? On rc2 with dwc 1,23/2.0 and I can't step down but I've never tried on the stable. Will roll back after this print and check.

Edit: just read that M208 is stopping it from going below Z0. What a strange limit to have. Well then it's not a firmware issue atleast since I have M208 set to Z0.

ben_van

@dc42
Just did a few tests..
Everything works as expected for G0 moves if the feedrate set in M203 is higher than 60mm/min. If I set the max feedrate lower than 60mm/min in M203 for any axes, G0 moves will still request a speed of 60mm/min.

I spotted to minor issues that have nothing to do with your minimum-speed-issue though:

M350 E64 I1         		      ; Configure microstepping with interpolation

Duet Wifi's TMC2660 only support interpolation with x16 microstepping. The above command won't do any harm but it will be "only" at x64 microstepping and won't be interpolated to x256.

M563 P1 S"Camera"
G10 P0 R0 S0                 ; Set initial tool 0 active and standby temperatures to 0C
G10 P1 X-1 Y-0.6;

There is a typo or copy-and-paste error in the middle line of this block. You define tool 1 but the middle line is still for tool 0.

ben_van

@wilriker Ah thankyou for pointing this out. The G10 for tool 1 was a typo from copy/paste. I guess I never noticed since i don't have any heaters bound to the tool anyway. As for the M350 extruder microstepping, I will change to the following:
M350 X256 Y256 Z256 E256 I0
Not sure why I didn't have it written like that before..

gavatron3000

@dc42 the m291 isn't unlocking a tool change still when called. Or is this impractical to do within a tool change?

We don't recommend using native x256 microstepping. You will be limited to low speeds if you do, because generating the step pulses will use up too much processor time. It may be OK for a CNC machine, but not for a 3D printer.

I understand the computational expense of doing this.. going fast is the last thing i want Most of the stuff made with this machine is seldom larger than 1mm, at speeds less than 50mm/min, and we have never experienced speed issues being limited by the CPU. This doesn't solve the G0 problem though..
To give you an idea of why this matters, here is a sample pic of one of the things we can do with this machine + duet . It's too small to see properly with the naked eye.

@ben_van looks interesting, but what the heck is that?

It is a generic 2D scaffold used for cell culture. Tissue engineering is not my field of expertise but for the people I am working with it is. This is just a test print to show we are working on a scale smaller than that of a stem cell, and about the size of a T-cell.
Cells are present while this structure is printed and are encapsulated inside the bio-compatible gel, where they then grow/multiply inside it, as it is like food for them. I like to think of it like bread crumbs, where we can coax the cells to grow and develop in a very controlled manner.
Whilst i can't dive into many specifics of how everything works until something is published, I can say that we have been getting some very good results
The benefit of using all open source software is once the groundwork is in place for this method, we can easily use readily available 3D printer slicers to make any micro 3D structure straight from a CAD model, and hopefully be able to provide this to people wanting to experiment without the $100k+ pricetag that comes with anything with the word 'bio' in it.
